Ethernet cable is a standardized communications protocol for local area network (LAN) transmissions. It was developed in the 1970s at Xerox PARC and became an international standard of ISO/IEC 11801 in 1991. Ethernet has evolved to become the de facto global industry standard, but many other protocols exist including Token Ring and Fiber Channel which are often used alongside or instead of it.
The Ethernet Cable consist of four pairs of wires twisted together into what looks like zip cord: two copper conductors called “twisted pair” that carry data and electrical power; insulation wrapped around each wire’s bundle forming the insulator known as dielectric; another layer called protective sheath surrounding all bundles making up outer conductor; metal shielding.
A twisted pair consists of two insulated conductors which are twisted together for the purposes of canceling out interference from both external sources and electromagnetic induction.
The wires in a cable twist around each other to form pairs, with an individual wire’s twists being right-handed or left-handed depending on its position in the pair. The twists shorten the apparent length of a cable by half while doubling it when compared to a reference without twisting. Each end has been assigned one color, typically used as green and orange but also commonly distinguished as blue/white (for example during initial installation).
How these Cables work?
These cables are a means of connecting two different devices together for communication from one to the other. These cables typically use electrical signals as their form of communication because it is easier and cheaper than using optical or radio waves which would require broadcasting hubs, amplifiers, receivers/transmitters etc..
These wires inside these Ethernet cable come in bundles with each bundle containing pairs. They contain four twisted copper wires that have been wrapped around themselves many times making them very thin and easy to bend into any shape desired without causing damage since there is no insulation on this wire like you see with typical power cords.
Each end has an RJ45 connection which looks similar to a phone jack except it usually contains eight pins instead of just two contacts (four pair). The other end will have a similar RJ45 connection that is designated to receive the pins from the other side. There are also two different colors typically green and orange but sometimes blue/white used for identification purposes so you can easily tell which port belongs to what device if multiple devices are connected in one area or behind another piece of equipment where it may be impossible to see them all.
These cables are very easy to install, just plug both ends into their respective ports on each device then done! However, there is more work involved when needing these connections outside since they need an outlet close by then installing some sort of connector at the desired location before connecting your Ethernet cable between them.
Dose Ethernet Cable Cables Go Bad?
As time goes on these cables can go bad over time if they are exposed to the elements around them whether it be excessively hot or cold temperatures. If this is not properly taken care of then oxidation could begin accumulating over a period of time which will cause a loss in signal strength and potentially speed as well.
These Ethernet cable also have an expected life span for their intended use before they should be changed out, usually anywhere from five to ten years depending on how much traffic runs through them but sooner rather than later because even though you may still see data running through at full speeds your equipment doing the actual processing might not due to weak signals being sent back and forth between each end that needs those stronger signals in order to process all that information.
Do not use these types of cables for outdoor purposes or run them through conduit, they are meant to be used indoors only and should never be exposed to any type of moisture at all because it will cause oxidation even faster than before which can lead to shorts in the wire that could seriously injure someone if touched.
When you’re ready to purchase Ethernet cable make sure you get a quality product from your supplier otherwise this may end up being an expensive mistake!
Why Ethernet Cables Are Used?
These types of wires are used throughout many different types of networks because they can be easily adapted to use on telephone systems and existing cables already running through buildings which makes updating much easier than if a new technology came about having to dig up all those miles of wiring before installation could even begin!
As mentioned earlier these Ethernet cables consist of four pairs of copper conductors wrapped around each other making them very thin but also strong enough where pulling won’t damage them and one end will contain a pair of contacts in the shape of an RJ45 jack that is eight-pin (four pairs) while the other side contains exactly the same thing but it’s just reversed.
